Q: Why does my check engine light come on

asked by on October 12, 2017

When I drive my truck long enough for the engine to heat up the check gauges light comes on with I'm stopped the only way it goes off is if I'm pushing the gas. The oil pressure gauge hits zero. All of my gauges jump. And for the first time this morning I left home drove it a few mins up the road and cut it off to go into the store for like 2 mins came back out cranked it up and left again my head lights would not work I flipped my high beams on and off didn't work then I turned them on and off completelya few time and they came back on. It always smells like gas even when its shut off and just sitting.
